I'm not sure how stiff the stock needs to be. Is it touching while you're shooting? Or is it just one of those OCD things where when you push it by hand and it touches so it messes with your mind? I have an older 116 FLCSAK in 30-06 that has been just plain stupid accurate right out of the box for the last 17 years. It'll put a full mag of 4 rounds through the center of a quarter at 100 yards darn near every time with my handloaded ammo shooting from bags. Well I did adjust the trigger but have replaced no parts. If it were touching without applying pressure relieving the offending portion of the stock may be an option for you. there's always aftermarket if you cant get it right. Good luck
